As further evidence that real estate is a local business, let’s take a look at the housing market in Japan today. It’s a very unique market.
According to this Freakonomics podcast, 50% of all single family houses in Japan are demolished by the time they reach 38 years old. That’s their half-life. By contrast, in the US, this number is 100 years.
The reason for this is rapid depreciation. Real property typically consists of two things: land and the building. Land doesn’t depreciate. But the structure sitting on the land does.
In Japan, the building or structure is thought to be fully depreciated (and therefore worth nothing) after about 30 years for a single-family home and after about 40 years for an apartment/condominium.
The result is that there’s virtually no resale housing market. When somebody buys a house, it is usually torn down and completely rebuilt. It’s a uniquely Japanese phenomenon.
